AP CSP Unit 3 Study

Comment

form of program documentation written into the program to be read by people

and which do not affect how a program runs.

Debugging

Finding and fixing problems in an algorithm or program.

Development Process

the steps or phases used to create a piece of software. Typical

phases include investigating, designing, prototyping, and testing

Documentation

a written description of how a command or piece of code works or was

developed.

Event

associated with an action and supplies input data to a program. Can be generated

when a key is pressed, a mouse is clicked, a program is started, or by any other defined

action that affects the flow of execution.

Event Driven Programming

some program statements run when triggered by an event,

like a mouse click or a key press

Input

data that are sent to a computer for processing by a program. Can come in a variety

of forms, such as tactile interaction, audio, visuals, or text.

Output

any data that are sent from a program to a device. Can come in a variety of forms,

such as tactile interaction, audio, visuals, or text.

Pair Programming

a collaborative programming style in which two programmers switch

between the roles of writing code and tracking or planning high level progress

Program Statement

a command or instruction. Sometimes also referred to as a code

statement.

Program

a collection of program statements. Programs run (or “execute”) one command at

a time.

Sequential Programming

program statements run in order, from top to bottom.

User Interface

the inputs and outputs that allow a user to interact with a piece of software.

User interfaces can include a variety of forms such as buttons, menus, images, text, and

graphics.

All computers and applications have the ability to:

Input -> Store Data -> Process Data -> Output

why are design specifications created?

so that the programmers know the purpose of the app and how users will interact with the final product
